You can secure a large outdoor space with a Ring outdoor camera. Choose a wireless camera with batteries and put it wherever you like. For an extra long battery life, you can choose an outdoor camera with a solar panel. You can also choose a wired video doorbell so you don't need to worry about the battery life at all. Most Ring outdoor cameras have a spotlight, which automatically switches on when it detects movement. That way, you can see where you're walking and you can scare off unwanted visitors.
